At our institution, injectable nitroglycerin (TNG) has been employed dur ing cardiac catheterization since 1976. Initially, it was primarily used in pa tients undergoing a provocative test for coronary spasm with ergonovine maleate. After the initial favorable experience, the use of injectable TNG became routine. 1,2
